To all whom it may concern:

Be it known that 1, CHARLES GIBBs, a citizen of the United States, residing in borough of Bronx, city of New York, in the county of New York andState of New York, have invented certain new and useful Improvements in Type-Writin Machines, of which the following is a s eci cation.

This invention re ates to the type-bars and hangers of writing machines, and particularly to that classiof hangers disclosed in my copending application No. 382,665, filed July 8, 1907 in which the hanger is in the form of a thin plate and is fastened in a radiating groove, each hanger having an individual lock or fastening device, in the form of a cam mounted in the same slot as the hanger and rotatable to lock and unlock the hanger.

The principal object of the present improvements is. to facilitate the attachment and detachment of the hanger, and to provide for looking it securelyin place.

I provide in a type-bar segment two pins or seat-rods for the hanger, each rod being curved to a ree with the curvature of the segment, an eachhanger having two hooks or hook-shaped slots to engage said seat-. this improvement, the lace upon the segment temporarily while t e locking cam is swung upclear therefrom, and it is rendered possib e to attach and detach the hanger without being obstructed by said cam, owingto the use of the two seat-rods and two hooks; moreover the cam is enabled to lock the hanger securely in place. Y

In the accompanying drawings, Figure 1 is a sectional side elevation of a front strike the Underwood class, showing my improvements. applied thereto.

of the hanger and'typebar. Fig. 3 is a sectional fragmentary'view of the segment, hanger and type-bar, the ban or locked in position. Fig. 4 is a view hanger will set in of detaching and attaching the hanger. 1 F ig. 5 is a sectional front perspectiveview of a type-bar segment, hanger and type-bar, the hanger locked in position.

Type-bars 1 are caused by key-levers 2 and bell-cranks 3 to swing up'about pivots 4 to strike against 'the'front side of a platen 5; the type-bars being pivoted face-wise. or-in in the formor eccentric cams slots 8 and pivoted upon a common fulcrum *eccertrio under edges of the cams.

this being .Each t any other suitable manner upon portions 6 of hangers 7,

depending or extending outwardly and down from the segment. The slots or sockets 8 are out completely through the bottom edge of the segment as seen clearly at Fig. 5, and the hangers 7 are in the form of thin plates which fit snugly in the slots 8. Preferably the cheeks or faces of the hanger are parallel throughout, and in order to seat the same securely, up er and lower curved rods 10, 11 are secure upon the rear side ofthe-se ment along its lower edge, and slotted portion of the segment. may be secured in any suitable manner, as by thrusting them "endwise in undercut grooves 13, 14 formed in the rear of, the segment. Each hanger has in its lower portion notches or slots 15, 16 which are hook-shaped, at their upper portions, as at .17, 18, to catch over and fit tightly upon the seat-rods 10, 1.1, whereby the hanger and type-bar may be supported temporarily until locked by means of a device hereinafter described. A fingerintersect'the piece 19 may project forward from the body of the hanger to be used in detaching the same from the segment.

The hangers are provided with individual locking devices, this instance illustrated 20 fitting in the rod 21 mounted in an undercut groove formed in the segment above the hangers, the latter having bearings 22 to receive the Each of the latter has a handle 23 which may be swung downwardly and forwardly to press down the hanger upon its seats .10, 11 the hanger being cammed immovably against both of said seats.

To detach the type-bar, it is only necessary to'swing up the cam lever, Fig. 4, when the finger-piece 19 may be rasped and the hanger 7 lifted to enable the hooks to clear the rods 10,11, whereupon the hanger may be, drawn forwardly out of the, slot, Fig. 4, an extremely quick operation. e-bar may have a heel 24 to press rearwar ly the usual universal bar 25.. It will be seen that the pressure of the cam 20 is in a downward direction, which not only forces the hanger down upon the seats, but

which are secured in radiating slots 8, formed m a segment 9, said portions 6 Said rods 10, 11

also tends to swing the hanger rearwardly about the upper seat 10 into forcible engage ment with the lower seat 11.

Having thus described my invention, I claim:

1. A t pewriting machine having a segment with two seats, a type-bar h'anger with two hooks to engage the seats, and means to hold the hooks against said seats.

2. A typewritin machine having a segment, a type-bar hanger to engage it, and means to press the ban er home, said means being releasable and when released clear of the horizontal lme of the ban er to allow removal of the han e horizontal y.

.3. A.typewritin maci nehaving' a seg-. ment, a type-bar anger to engage it, and means to press the hanger home? said means being releasable and ying when released clear of the horizontal line of the hanger and above the same to allow removal of the hanger horizontally 4. A typewritmg-machinehavinga segment, a type-bar-hanger to engage it, and a ssaeso releasable means above the hanger and enaging its upper edge to press the hanger ome, said means lying when released clear above the u per edge of the ham er to allow removal of t e hanger horizontal y. 5. Atype-bar hanger having two hooks to engage supporting points, and a substantially strai ht upper edge to be engaged by a clampevice.

6. A type-bar hanger having two hooks at its rear edge to engage su portlng points, and

a seat forward of such e ge to be engaged by a clamping device.

7. Av typewriting machine having a segment with two bearing-points, a type-bar hanger having two downwardly facing hooks respectively -to engage the bearing points, an means to press the hanger downward with the hooks against the bearing points.
